Hi,

I don’t think language pragmas are about choice in that sense. Either
we don’t want the feature (then we’d reject it), or we want it to
eventually become a viable default (at least for add-on extensions like
this). So at some day I expect GHC20xx to allow both \case and \cases.
Nobody forces to to _use_ \cases in your code, however!

The question is more about: do we want extensions to evolve over time,
or be more immutable (I don’t think we want to commit to full
immutability).

Cheers,
Joachim
